Time and place of tidal observation in Jiuxi

The tidal time of Jiuxi is from the first day to the fifth day and the fifteenth day to the twentieth day of the lunar calendar, and the location is near Jiuxi, Xihu District, Hangzhou.

There is an obvious bend in this reach, and the tidal bore passes near here, sometimes there is an undercurrent, and there is no obvious tidal head, which is not easy to detect and is easy to cause casualties, so attention should be paid to it. During the spring tide, the tidal head can be seen, but the tidal potential is gradually decreasing. Because there is a downstream dam upstream of Jiuxi exit, the tidal bore is blocked and then pushed by the subsequent tidal bore. After crossing the downstream dam, it enters the coral sand sluice section, and the coral sand reservoir and the river bank form cloth pockets, and the tide seems to be caught in a net.

At the corner where the dam intersects, the tides collide with a loud bang, and the tide head goes straight into the sky, and a water column rises, the lowest is two or three meters, and the highest can reach more than ten meters, causing the phenomenon of "foaming at the mouth", which is the most attractive tide in the close-range tide.

During the flood season in this area, there may be "resurgence" and "surge tide", and there is a danger that the tidal bore will cross the breakwater and cause casualties. Tides occur every day, and the best viewing time is from the first day to the fifth day and the fifteenth to the twentieth day of the first lunar month. Danger of tidal bore, please pay attention to the warning signs in the tidal observation area and obey the management of local moisture-proof management personnel.
